It’s well understood that internal combustion engines require valves for intake of fresh air and discharge of exhaust gases. Today, mechanically driven camshafts are used to control the gas exchange valves of four-stroke engines. They are often equipped with additional mechanisms, some of which are quite complex, that permit modifications to a valve movement pattern by the camshaft. But it increases friction and flexibility is still quite limited. To improve fuel economy and accommodate alternative fuels, engine makers need a new design that offers fast valve movements even at low speeds, adaptable strokes and cylinder-selective variable valve timing.
